4.3 Density and pressure

1 define and use density
2 define and use pressure
3 derive, from the definitions of pressure and density, the equation for hydrostatic pressure ∆p = ρg∆h
4 use the equation ∆p = ρg∆h
5 understand that the upthrust acting on an object in a fluid is due to a difference in hydrostatic pressure
6 calculate the upthrust acting on an object in a fluid using the equation F = ρgV (Archimedes’ principle)
